c++ - 如何获取类函数名称列表？ Qt C++

Question

例如我有这段代码:

class MyClass : public QObject
{
    Q_OBJECT
public:
    void MyClass()
    {
    QStringList selfFunctionList;
    //Get functions list
    qDebug()<<selfFunctionList;
    }
    void function1(){}
    void function435(){}
};

如何设置“function1”和“function435”的 selfFunctionList 列表？

Answer 1

您可以为此使用staticMetaObject。

class Test : public QObject
{
    Q_OBJECT
public:
    explicit Test(QObject *parent = 0) :
        QObject(parent)
    {
        for (int n = 0; n < staticMetaObject.methodCount(); n++) {
           functions.append(QString::fromLocal8Bit(staticMetaObject.method(n).name()));
        }
        qDebug() << functions;
    }

signals:
    void testSignal();

private slots:   
    void privateTestFunction() {}

public slots:   
    void publicTestFunction() {}

private:
    QStringList functions;
};

一个条件，函数需要声明为槽或信号。

输出:

("destroyed","destroyed","objectNameChanged","deleteLater","_q_reregisterTimers",
"testSignal","privateTestFunction","publicTestFunction")
